BACKGROUND OF THE INVENTION Field of Invention

The present invention pertains to class 15 (brushing, scrubbing, and general cleaning); subclasses: 1.52 (Hand implement), 302 (with liquid or other cleaning material application to work), 250.451 (Specific backing member), 207.2 (Bristle configuration or composition), 209.1 (Wiper, dauber, polisher), 226 (Strands); and also class 139 subclass 391 (pile)

Background Art

The usefulness of the present invention originated from addressing problems found in prior art handheld cleaning implements intended for showering and bathing.

A multitude of hand held cleaning implements have been developed for use during bathing and showering. Generally, natural or synthetic sponges, cotton or microfiber washcloths, loofahs and net sponge-poofs have been the most common options. Each of the mentioned prior art implements have a number of deficiencies accompanying their use. Sponges have a form consisting of various openings or pores which attract dirt, soil, skin, and hairs. A sponge's form makes it difficult to rinse the sponge of dirt, soil, skin and hairs after use which decreases or eliminates its reusability. Washcloths have a form that is prone to crumple and bunch up while in use; which reduces its effective surface area, ability to lather and overall ease of handling. A washcloth's form makes it difficult to rinse the washcloth of dirt, soil, skin and hairs after use. Loofahs have a form consisting of various openings or pores which attract dirt, soil, skin, and hairs Prior art U.S. Pat. No. 6,656,565B2 (Harrison). A loofah's form makes it difficult to rinse the loofah of dirt, soil, skin and hairs after use which decreases or eliminates its reusability. Net sponge-poofs; also referred to as a loofah/luffa, have a form consisting of folded netting which attracts dirt, soil, skin and hairs Prior art U.S. Pat. No. 5,916,586A (Villa). A net sponge-poof's form makes it difficult to rinse the net sponge-poof of dirt, soil, skin and hairs after use which decreases or eliminates it reusability Prior art U.S. Pat. No. 7,589,053B2 (Larsen).

There are a variety of cleaning implements which are described as having both a surface that is soft and a more abrasive surface to exfoliate. These hybrid implements have forms characterized by deficiencies similar to those present in the already mentioned prior art cleaning implements. For example, Prior art U.S. Pat. No. 5,412,830A (Girardot) is a dual textured implement that contains two main elements; a coarse diamond mesh scrim surface and a softer knitted material surface, which when combined form an implement that resembles a netted pouch; resulting in an implement that is more likely to trap soil, dirt, skin and hairs; which is difficult to rinse and reuse.

Prior art U.S. Pat. No. 5,491,864A (Tuthill) is a gathered hydrophobic diamond mesh scrim with circumferential pleats. The disclosure states the invention can be quickly rinsed and dried. It is not clear what the invention can be quickly rinsed of. Based on the invention's form; which resembles a flat batt of netting, it would be difficult to rinse and reuse the described implement. The flat diamond mesh scrim may be easier rinsed of liquids; such as soap, but a gathered diamond mesh scrim with circumferential pleats has a form made up of openings and slots that are difficult to rinse of soil, dirt and hairs.

There are known other prior art cleaning implements. Prior art Stay Clean Scrub Sponge; sold by Scotch-Brite™, is a dual surfaced device. It contains a coarse surface and a sponge surface; and is advertised as a scrub sponge with a surface that will not trap food. The Scrub Sponge's coarse surface does not allow for a comfortable or gentle use during showering and bathing. The sponge surface is porous; whose openings increase in size after each use; as the sponge wears down. The sponge surface also does not have desirable drying characteristics. Distinguishing attributes and advantages of the present invention in relation to implements such as the Scotch-Brite™ Scrub Sponge will be illustrated and explained in the detailed description of the invention. Prior art Scotch-Brite™ Scrubbing Dish Cloth; also sold by Scoth-Brite™, is advertised as a cloth that rinses clean. It is not clear what the cloth can be rinsed clean of. Based on its slack form, the device would experience deficiencies similar to those demonstrated by any ordinary washcloth.

BRIEF SUMMARY OF THE INVENTION

A reusable handheld cleaning implement comprised of a flat, perforated, semirigid, pliable, semiresilient backing made of water resistant material. A plurality of single, solid, linear, vertical, soft, pliable, semiresilient, smooth, non-open looped strands are connected to the backing forming both the top and bottom surface of the implement. A tether is connected to the implement.

An objective of the present invention is to provide a reusable handheld cleaning device demonstrating desirable rinsing characteristics in regards to foreign matter. The spirit of the present invention has a utility that considers multiple uses that may benefit from a comfortable reusable handheld cleaning device with advantageous rinsing attributes.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to the drawings in order to better understand the present invention, its objectives, elements, usefulness and advantages.

FIG. 1, there is shown the preferred embodiment of the present invention which provides a reusable handheld cleaning implement and is generally indicated as implement 100. Implement 100 is comprised of backing 104, strand 102, a top surface 108, a bottom surface 110, a perimeter 106 and a tether 112.

FIG. 2, there is shown backing 104 of implement 100. Backing 104 is a single solid non abrasive piece. More specifically, backing 104 and the backing of alternate embodiments of the present invention exclude a backing made of multiple layers that may create slots, pouches or an accordion like structure; which is contrary to the spirit of the invention; resulting in an implement that is difficult to rinse and reuse. Backing 104 is flat and constructed to be semirigid, pliable and semiresilient. The described requirements of backing 104 are an essential and fundamental part of the present invention; necessary to solve problems related with prior art washcloths and other slack handheld implements lacking a specific backing member; that are intended for a bathing and showering application. Implement 100 is adequately rigid and resilient; to resist bunching and crumpling as it is casually moved along the applied surface, while also being pliable in order to allow implement 100 to be contoured to the applied surface. The measure or degree of semirigidity and semiresilience are at levels that allow for any ordinary person to bend, flex and operate implement 100 with one hand. The semirigid flat surface of backing 104 minimizes or eliminates folds and pleats; enabling an intended user to rinse the device of dirt, soil, skin and hairs by holding implement 100 in one hand or placing implement 100 on a relatively flat surface; while it is sprayed by the water from a showerhead or hose. The semirigidity of backing 104 also allows for a user to better handle and rinse implement 100 after use by rubbing implement 100 between two hands under running water; as implement 100 resists bunching and crumpling.

Backing 104 is comprised of multiple perforations 202. Perforations 202 are located throughout the backing; adjacent to the strands. Perforations 202 are permeable, allowing air and water to pass through backing 104; more specifically to ensure that backing 104 is not watertight. Perforations 202 creating large gaps or openings in backing 104 are not within the scope of the invention. For example, Prior art U.S. Pat. No. 6,656,565B2 (Harrison) incorporates linear openings that are more likely to trap foreign matter such as a hair; which can entangle itself through and around the large openings in the backing; resulting in a device that is difficult to rinse and reuse. Perforations 202 are less than or up to 1 mm in diameter; and perforations are less than or up to 2 mm in diameter for alternate embodiments of the present invention. Perforations 202 aid implement 100 in producing a lather as well as improve the implement's overall rinsing and drying traits. Perforations 202 further increase the usefulness of implement 100 by allowing water and soap to pass through to the opposite side of the surface being applied; enabling the user to more easily alternate between surfaces during use.

Backing 104 is constructed of a water resistant material as to supplement the semirigidity, pliability and semiresilence of backing 104. A water resistant material benefits backing 104 and alternate embodiments of the present invention by minimizing the change in measure of rigidity, pliability and resilience between a wet or dry application. The backing of the present invention may also be comprised of a water proof material. A water resistant material also contributes to the behavior of perforations 202; minimizing their fluctuation in size when implement 100 is exposed to liquids. A water resistant material further benefits the present invention in relation to the thickness of backing 104. A water resistant backing that satisfies the semirigidity, pliability and semiresilience requirements of the present invention can be considerably thinner than a backing that is not water resistant. A thin backing minimizes the volume of perforations 202; which further improves the overall ability of implement 100 to be rinsed and reused. A water resistant material also improves the drying qualities of implement 100.

Perimeter

106 and implement 100 are square in shape. Embodiments of the present invention can include rectangular and circular shapes. Perimeter 106 has a non abrasive surface. The present invention excludes a perimeter that is abrasive or has a form that is constructed with angles that may result in a device that is difficult to rinse and reuse. The dimensions of backing 104, implement 100 and alternate embodiments of the present invention are restricted. For example, common bath towels; which measure approximately 30 inches by 60 inches, are not within the scope of the invention. The size of a bath towel contradicts an objective of the present invention; to be an easily rinsed handheld implement. In addition, the dimensions of a bath towel create too much conflict regarding the balance of semirigidity, pliability and semiresilience to make it an effective and demonstrable handheld cleaning implement within the scope of the invention, Prior art U.S. Pat. No. 8,678,044B2 (Rabin).

Spherical forms are also not within the scope of the invention, Prior art U.S. Pat. No. 6,026,534A (Gonda), due to lacking a flat surface.

The preferred dimensions of backing 104 are 5 inches by 5 inches with a thickness of 1 mm.

There are a variety of materials that can fulfill the requirements of backing 104. Common polymers such as polyethylene and polypropylene are suitable examples. It is preferred that the material chosen is hypoallergenic and has tolerances which allow it to be exposed to household soaps, detergents and bleach; machine washed and machine dried. The providing of example material is intended to serve as an aid to better understand and grasp the scope of the invention, not to limit the present invention to one specific material.

FIG. 3, there is shown strand 102 of implement 100. Strand 102 consists of a top end 302 and a bottom end 304. Bottom end 304 is connected to backing 104 and top end 302 is free and unattached. A plurality of strand 102 comprises both the top surface 108 and the bottom surface 110 of implement 100. Alternate embodiments of the present invention may include an implement whose perimeter is surfaced with strand 102. Strand 102 is linear; more specifically, not a strand that has a form consisting of bends and or twists. Top end 302 is vertical or vertically aligned to bottom end 304; as to exclude a strand that is horizontally aligned to backing 104; which may create an area between strand 102 and backing 104 that is difficult to rinse, Prior art, U.S. Pat. No. 9,267,232B2 (Gilman).

Strand

102 is constructed to be a single solid strand and more specifically not an open looped strand. Open looped refers to a strand that consists of an opening or openings. This includes a strand that may have multiple origins from a backing; then those origins loop, connect, mesh, intertwine or cross with each other to form a strand that is not solid; that has a surface made up of openings and slots; similar to a net or a tree and its branches. Such a strand is not within the scope of the invention. Its form creates a surface that clings to skin, dirt, soil, hairs and is difficult to rinse and reuse.

Strand

102 is constructed to have an overall smooth surface; not consisting of projections or indentations that create a ridged or ribbed surface that is clingy and traps foreign matter; that is difficult to rinse. A smooth solid strand reinforces an objective of the invention; to provide an implement that is easier to rinse and reuse.

Strand

102 is soft, pliable and semiresilient; as to provide a gentle non abrasive effect during application; comparable to men's synthetic shaving brushes and synthetic cosmetic brushes. A pliable strand also minimizes or eliminates the probability of foreign matter; such as hair, to wrap around and entangle itself on the strands. The described strand is effectively pliable; to support the already mentioned examples of how implement 100 can be rinsed and reused; with water sprayed from a nozzle or by rubbing implement 100 between two hands under running water. Strand 102 further improves the lathering qualities of implement 100; an objective of the present invention, allowing the intended user to comfortably produce a lather during a showering or bathing application.

It is an objective for the strand of the present invention not to capture or cling to dirt, soil, skin and hairs. Prior art, U.S. Pat. No. 6,085,380 (Gonda), U.S. Pat. No. 8,500,211B2 (Lindblad), U.S. Pat. No. 6,305,431B1 (Fenkes), U.S. Pat. No. 8,156,967B2 (Huffstickler), are examples of inventions that are contrary to the spirit of the present invention; containing elements that amplify the ability to cling to foreign matter.

The strand of the present invention is restricted to a length equal to or less than 1 inch and a diameter equal to or less than 1 inch. Strands cannot be spaced more than 1 inch from one another. Strands spaced more than 1 inch apart do not create an effective or useful surface within the scope of the invention.

The backing of the present invention; as described, allows a person skilled in the pertinent art to make various changes to the length, diameter and spacing of the strand; while remaining within the spirit of the invention.

It is preferred that strand 102 is a cylindrical monofilament with an uncompressed length of 5 mm and uncompressed diameter of 1 mm; spaced at 16 strands per square inch.

There are a variety of materials that can fulfill the requirements of strand 102. A synthetic material; such as Nylon, is one suitable example. It is preferred that the material used for strand 102 is hypoallergenic and has tolerances which allow it to be exposed to household soaps, detergents and bleach; machine washed and machine dried. The providing of example material is intended to serve as an aid to better understand and grasp the scope of the invention, not to limit the present invention to one specific material.

FIG. 1, is shown tether 112, attached to implement 100. Tether 112 improves the handling characteristics of implement 100 and provides a means to hang implement 100. Tether 112 can be constructed from a variety of materials; Nylon is one example. It is preferred that the material used for tether 112 is hypoallergenic and has tolerances which allow it to be exposed to household soaps, detergents and bleach; machine washed and machine dried. The providing of example material is intended to serve as an aid to better understand and grasp the scope of the invention, not to limit the present invention to one specific material.

FIG. 6, there is shown an alternate embodiment of the present invention; indicated as implement 600, which incorporates lining 502 wrapped around perimeter 106. Lining 502 is provided as a means to resolve issues or concerns that may be contrary to the spirit of the invention; arising from a certain method of construction and assembly of implement 600; or alternate embodiments of the present invention. For example, lining 502 may serve as a means to secure the edges or ends of two individual backings that are connected together to form a single backing; or smooth the abrasive edges of a single backing that is formed by two backings that are secured together. Lining 502 can also serve to smooth the abrasive edges of a molded backing; or smooth a perimeter that may be abrasive due to the method in which the backing is cut from a larger piece of material. The present invention does not limit lining 502 to a specific application. It is preferred that lining 502 maintains the flat surface of the backing as described and remains within the overall scope of the invention.

Lining 502 can be constructed from a variety of materials; Nylon being one suitable example. It is preferred that the material used for lining 502 is hypoallergenic and has tolerances which allow it to be exposed to household soaps, detergents and bleach; machine washed and machine dried. The providing of example material is intended to serve as an aid to better understand and grasp the scope of the invention, not to limit the present invention to one specific material.

It is understood that the various methods to assemble the components comprising the present invention are a routine detail, and that the essence of the invention has been described so that any person in the relevant field can fabricate said invention without extensive experimentation.

While the described invention originated from addressing problems associated with handheld implements intended for showering and bathing, it is understood that this does not limit the invention to a specific application. The aforementioned description contemplates any alternative use that may benefit from the present invention; such as a dusting and or wiping application. It is also obvious that while embodiments of the present invention have been illustrated and described, it is apparent to those skilled in the art that various changes may be made without departing from the spirit and scope of the invention; and it is intended that all such compliant modifications are contained within the specification and the appended claims.
